BIS(METHYLTHIO)(TRIMETHYLSILYL)METHANE Usage And Synthesis

Physical properties

bp 67–70°C/10 mmHg.

Uses

Bis(methylthio)(trimethylsilyl)methane is a reagent used for synthesis of bis(methylthio)ketene acetalsfrom aldehydes and ketones;acyl anion synthon for conjugateadditions to enones and enoates;useful for one-carbonhomologations.
The bis(methylthio)keteneacetals are useful synthetic intermediates because they are readilyconverted into S-methyl thioesters (eq 9) or the correspondingcarboxylic acids and esters.

Preparation

prepared from lithiobis(methylthio)-methane by silylation with chlorotrimethylsilane (eq 1).Bothbis(methylthio)methane and chlorotrimethylsilane are commerciallyavailable.
